在错误的活动中点击edittext重定向内的搜索项，它不会打开与之关联的活动。它打开与其他列表项相关联的其他活动，但不是我点击其中一个。
以下是我的完整代码：
public class Tabtwo extends Activity implements OnItemClickListener {
ListView listView;
TextView txt;
ArrayAdapter<String> adapter;
// Search EditText
EditText edtSearch;
// Array of strings storing country names
String[] countries = new String[] { "Admin Cost", "Affinity Diagram",
"Analyse", "Apprasal Costs", "Assessment of Stakeholders",
};
// Array of integers points to images stored in /res/drawable-ldpi/
int[] flags = new int[] { R.drawable.admin, R.drawable.affinity,
R.drawable.analysis, R.drawable.appraisal, R.drawable.assessment,
};
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabtwo);
// Each row in the list stores country name, currency and flag
List<HashMap<String, String>> aList = new ArrayList<HashMap<String, String>>();
for (int i = 0; i < 4; i++) {
HashMap<String, String> hm = new HashMap<String, String>();
hm.put("txt", countries[i]);
hm.put("flag", Integer.toString(flags[i]));
aList.add(hm);
}
// Keys used in Hashmap
String[] from = { "flag", "txt" };
// Ids of views in listview_layout
int[] to = { R.id.flag, R.id.txt };
// Instantiating an adapter to store each items
// R.layout.listview_layout defines the layout of each item
final SimpleAdapter adapter = new SimpleAdapter(getBaseContext(),
aList, R.layout.listview_layout, from, to);
// Getting a reference to listview of main.xml layout file
ListView listView = (ListView) findViewById(R.id.listview);
edtSearch = (EditText) findViewById(R.id.Search_box);
txt = (TextView) findViewById(R.id.txt);
listView.setOnItemClickListener(this);
// Setting the adapter to the listView
listView.setAdapter(adapter);
listView.setTextFilterEnabled(true);
listView.setOnItemClickListener(this);
edtSearch.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence s, int start, int before,
int count) {
adapter.getFilter().filter(s);
adapter.notifyDataSetChanged();
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void afterTextChanged(Editable s) {
}
});
}
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
// TODO Auto-generated method stub
if (position == 0) {
Intent int0 = new Intent(getApplicationContext(), Admincost.class);
startActivity(int0);
}
if (position == 1) {
Intent int1 = new Intent(getApplicationContext(), Affinity.class);
startActivity(int1);
}
if (position == 2) {
Intent int2 = new Intent(getApplicationContext(), Analyse.class);
startActivity(int2);
}
if (position == 3) {
Intent int3 = new Intent(getApplicationContext(),
ApprasalCosts.class);
startActivity(int3);
}
if (position == 4) {
Intent int1 = new Intent(getApplicationContext(), Assessment.class);
startActivity(int1);
} }
}
}
这是我的tabtwo xml文件。

用下面替换你的onItemClick方法并尝试..希望它有效..
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
TextView tv = (TextView) arg1.findViewById(R.id.txt);
String str = tv.getText().toString().trim();
if (str.equals(countries[0])) {
Intent int0 = new Intent(Tabtwo.this, Admincost.class);
startActivity(int0);
}else if(str.equals(countries[1])) {
Intent int1 = new Intent(Tabtwo.this, Affinity.class);
startActivity(int1);
}else if(str.equals(countries[2])) {
Intent int2 = new Intent(Tabtwo.this, Analyse.class);
startActivity(int2);
}else if(str.equals(countries[3])) {
Intent int3 = new Intent(Tabtwo.this, ApprasalCosts.class);
startActivity(int3);
}else if(str.equals(countries[4])) {
Intent int1 = new Intent(Tabtwo.this, Assessment.class);
startActivity(int1);
}
}

将此代码添加到TextView以及ImageView
android:focusableInTouchMode="false"
android:clickable="false"
android:focusable="false"
对于ItemClick，您可以使用 Tamilan

我和你有同样的问题。请尝试以下方法：
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// When clicked, show a toast with the TextView text
//(String) getListAdapter().getItem(position);
String city_id=map.get( (String) adapter.getItem(position) );
Toast.makeText(getApplicationContext(),city_id, Toast.LENGTH_SHORT).show();
Intent i=new Intent(MainActivity.this,DetailActivity.class);
i.putExtra("city_id",city_id);
startActivity(i);
}
});
